To all whom it may concern:

Be it known that I, ALBER'1 BALL, a cititaken in connection withtheaccompanying illustration of one specific embodiment thereof, while itsscope will be more particularly pointed out inthe appended claims In thedrawings,\Figure 1 is a side ele vation of a channeling machinestandard,

together with the attached reciprocating engine and crosshead, andembodying one form of my 1nvent1on; Flgl 21s a front ele-' vation of theparts shown in Fig. 1; Fig. 3

is an enlarged detailof the mounting of the rocker reverse lever 5 Fig.4 1s a section on the line .44 of Fig. 3, and Fig. 5 is a section on anenlarged scale taken through the auxiliary cylinder head on theirregular line 5-5, Fig. 2.

Referring to the drawings and to the einbodiment of my invention thereillustrated,

I have shown the tool standard A having an arched head (rand providedwith longitudinal flanged guides a, a.' The remain} ing parts of thechanneling machine are not herein shown, their specific constructionbeing immaterial for thepurposes of. the in: vention, but they maybe ofany suitable construction and the machine'is here assumed to comprise anordinary track chane. neler at the side of whichthe standard'A issupported inan upright, position {and in a fashion well-known in'the artso'thati the tool can cut the'usual channel groove at the side of themachine: as the latter" vanced along the track-way.

Slidably supported" upon the" guides a" of the standard are carriedtheengine cylinder B and the cross-head guide said cylinder and guidebeing bolted to a pair, offgibs a;

by an adjusting screw d which is journaled in the arched head a of'theframe and there held against longitudinal movement, and provided withany suitable means such the ratchet lever ol by which the screw v may beturned. This screw acts to move the cylinder and the attached guide inany suit able way, as through the medium of the fixed nut (not shown).

. In constructing the standard, which, it will be observed, has twouprightside members ,mergingfinto the arched head and insubstantiallythe same plane with thejou 'r- Y I nal bearing, for thescrew (that is to say the arched head is without substantial forwardoverhang), I preferably form the head ii1,

[tegrally with the body of the standard, as

by casting the same in a singlepiece. This 'I have; found in practiceconsiderably strengthens the arched'head and avo'idsdthe main bodyportion of the standard, thiszhav -q ing been the construction usuallyadopted in that type of channel'er employing the nonoverhanging screwsupport.

Bythe side of the engine cylinder Bis an interior valve (not shown) towhich is '85 located the valve cha'mber' E provided with imparted areciprocatory movement through Z the valve, rod 6 actuatedthroughconnee,

Reciprocatory movement is imparted to the valve stem 6 through itsjointed 'con-.

free end oflthe lever being ointed to a link 6 pivotajll-y connectedtofthe cross-head at 6 supportxattached to the'lower part of thecylinder head, such support thereby con-;'

siderablykobstructing the space below the cylinder head "and,preventingeasy access Q material to theobject of the invention here;

to the packing gland b. In the present construction I have materiallysimplified the mechanism by providing a boss or fulcrum support 6 at theside of the sliding cylinder-guide structure and herein, although notnecessarily, at the side of the crosshead guide itself. This removes theusual obstruction, heretofore necessitated by the pivotal mounting ofthe rocker reverse lever, from the space beneath the cylinder head andabout the stuffing box gland 7).

Referring more particularly to Figs. 1, 2 and 5, the piston at its upperend is provided with a tail-rod 9 (see Fig. which projects through theupper end of the cylinder and is slidably mounted in a sleeve or bushing71, the latter having a tapered seat in the auxiliary cylinder head H.The bushing h is held to its seat, and the open end of the auxiliaryhead closed, by means of the plug it threaded into the top of theauxiliary head. In addition to the guidance which is afforded by thepresence of the auxiliary head H serving to maintain the alinement ofthe piston and cross-head, the said auxiliary head also provides meansfor lubricating the tail-rod and thereby supplying lubricant to theengine cylinder. For this purpose there is formed in the auxiliary heada hollow chamber 7?, which, being separated from the tail-rod by thebushing it, forms an annular reservoir for the lubricant. This reservoirmay be filled or replenished through the passage 7L3 arranged in anoffset portion of the head and closed by the plug h Leading from thelower end of the reservoir is the lateral exit passage h (see Fig. 5')having connection through the valved passage h with an annular groove72. located opposite a series of apertures in the bushing which serve toconduct the lubricant to the surface of the tail-rod. The passage 72, isnormally closed by the ball valve it the latter, however, being raisedby superior pressure from beneath to permit the oil to pass to thetail-rod. Pressure is admitted intermittently at each forward stroke ofthe piston from the head end of the cylinder to the pressure chamber itsat the end of the tail-rod through a vertical passage (shown in dottedlines Figs. 1 and 5) formed in an offset portion 71- of the head anddirectly connecting the cylinder and the chamber it". When pressure isthus admitted it enters the groove 717 and lifts the ball valve it tothe space allowed for ball movement by the adjusting screw It (Fig. 5).When the ball is lifted oil passes to and within the bushing 71- and byreciprocation of the tailrod is carried to the cylinder, oiling theparts gradually as required, By adjusting the screw h the lift of theball and the feed of the oil may be regulated as desired.

While I have shown and described one form of my invention for thepurpose of illustrating the parts thereof, it is to be understood thatextensive departures may be made from the details of the described formwithout departing from the spirit thereof.
